(Reuters) - Campaigns to become the first U.S. states to legalize marijuana for recreational use in Washington and Colorado have raised $3 million ahead of a November vote, far outpacing the opposition.

Proponents of pot legalization in Washington state have raised nearly $2 million since the initiative qualified for the ballot in January, and about $1 million in Colorado since its measure earned a place on the ballot the following month, according to the most recent state campaign figures.

[...]opponents of legalization have so far fallen short in fundraising. State campaign figures show that Smart Colorado has raised the most of any anti-legalization group, but its 2012 total stands at less than $40,000.
